COMMON PROBLEMS
Five major problems :
1. PAIN2. STIFFNESS3. DECREASE IN MUSCLE
STRENGTH4. LOSS OF DEXTERITY5. LOSS OF LOCOMOTOR
ABILITY
PAIN
Pain is the priority problem.
STIFFNESS
Decreased flexibility Can be a result of pain, or of
disuse or it can be a result of pathophysiologic changes
DECREASE IN MUSCLE STRENGTH
a primary problems, as with some myopathic and neuropathic disorders, or it can result from prolonged bed rest or immobility
LOSS OF DEXTERITY
skilful use of hands or body
LOSS OF LOCOMOTOR ABILITY
Temporary or complete loss of the ability to move freely from one place to another or care for one’s self.
System Involved: Complications of
Immobility
CARDIOVASCULARMechanism:Failure of vessels in legs to
assume or maintain a state of vasoconstriction, resulting in pooling of venous blood.
Potential Complication:
Deep vein thrombosis (DVT)Pulmonary embolism (PE)Increase work load on heartDiminished cardiac outputDecreased ability to adapt to
erect posture
RESPIRATORY
Mechanism:Decrease movementDecrease stimulus to coughDecrease depth of
ventilation
Potential Complication:
Pooling of secretions in bronchi, bronchioles
Hypostatic pneumonia
SKINMechanism:Pressure or shearing forces
(two or more tissue layers sliding on each other or tissue sliding on another surface) disrupting or decreasing circulation to an area.
Potential Complication:
Skin breakdown (abrasion or decubitus ulcer)
GASTROINTESTINAL
Mechanism:Decrease bowel mobilityChange in dietary habitsDisadvantageous positioning for defecation
Potential Complication:
Constipation Impaction
MUSCULOSKELETAL MUSCLES
Mechanism:Disuse
Potential Complication:AtrophyWeakness
JOINTSMechanism:Limited motion leads to
muscle, tendon shortening
Potential Complication:ContractureFibrosis or bony ankylosis
around joints
BONESMechanism:Disruption of balance of
osteoblastic/osteoclstic activity with destruction of bone matrix and release of calcium.
Potential Complication:Osteoporosis
URINARYMechanism:Increase urinary pH,
increased citric acidPoor bladder emptyingPotential Complication:Renal stonesUrinary stasis
NEUROLOGIC
Mechanism:Loss of normal stimuli
Potential Complication:ConfusionRestlessnessForgetfulness
COMMON INTERVENTIONS
Common interventions:1. Rest, activity, joint protection,
energy conservation2. Assistive, supportive, and
safety devices3. Application of heat and cold4. Traction 5. Splinting and bracing
6. Positioning and transfer7. Exercise 8. Medications 9. Surgical interventions
Rest, activity, joint protection, energy conservationREST A therapeutic measure used in
many inflammatory and traumatic conditions of the musculoskeletal system.
However, too much rest can at times be as detrimental as too much activity.
Two Forms of Rest:
1. Absolute rest or no activity.2. Partial rest or limited
activity.
Nurse’s responsibility in helping the patient rest:
Help patient understand the meaning of “rest” as it applies to him or her.
Take over functions for the patient that would require use of body part beyond limits prescribed.
Teach the patient how to effectively use body parts not required to rest.
Gradually return functions to the patient when rest is no longer required.
ACTIVITY Activity, particularly in chronic
conditions, must be balanced with adequate rest.
Individuals who have pain with certain activities or increase pain and stiffness following certain activities must learn to recognize their tolerances and adapt their ADL accordingly.
• Nurses can help patients determine their activity needs in the following ways:
Teach the patient the advantages of continuing, but modifying, activity
Help the patient identify his or her own activity tolerances
Help the patient work out an activity schedule approximating rest/activity requirements at home.
Help the patient work through concerns about not being able to perform all activities he or she believes are necessary or desired.
Joint Protection & Energy Conservation
Individual with joint involvement and /or activity intolerances can learn to protect their joints and themselves from overuse, misuse, and stress by becoming aware of and practicing joint protection and energy conservation techniques.
Techniques:
Avoid positions of possible joint deformity
Avoid holding muscles or joints in one position for a long time
Use the strongest joints for all activities
Use joints in their best position, maintaining good standing and sitting posture
Conserve energy
Nursing Intervention:
Teach the patient to recognize the symptoms of overactivity.
Teach the patient appropriate energy conservation and joint protection techniques.
Encourage the patient to use those techniques in ADL.
Assistive, supportive, and safety devices Assistive devices
Viable for individuals who have impairement of upper and/or lower extremity function.
Some assistive devices for persons with motor impairments:
Supportive devices
Ambulatory aids Usually recommended for
persons who cannot bear weight on one or more joints of the lower extremities
•Some considerations regarding choice of device include:Axillary crutchesWalkersCanes
Safety devices
Enhance function and prevent accidents when normal function, balance, or dexterity are compromised.
Application of heat and coldHeat Used for relieving stiffness
and relaxing muscles and for analgesic effect and sedative effect.
Heat may be applied in a variety of ways:
Dry heatMoist heat
Cold Helpful in reducing or
preventing swelling, reducing pain, and relieving stiffness
Heat and cold should be applied with caution to any individual with decreased sensation, because that person will not be able to determine if damage is occurring.
Nursing intervention with heat and cold include:
Helping patient determine which type of application works best
Instructing patient about safety precautions to be observed with that method
Instructing patient about timely application of heat and cold depending on patient’s particular needs.
Assisting the patient with application.
Traction Used to help reduce contractures
or to relieve pain in the presence of muscle spasm.
It can be applied intermittently or constantly and usually in the form of skin traction, that is Buck’s extension, Russell traction, or pelvic traction.
Splinting and bracing
Purposes: Stabilize or support a joint Protect a joint or body part from external
trauma Mechanically correct dysfunction such
as footdrop by supporting the joint in its functional position
Assist patients to exercise specific joints
When patients need to use braces or splints, nurses need to:
Inspect patient’s skin after the orthosis has been applied for a short time to be certain it has caused no skin irritation
Notify orthotist if adjustments in the orthosis need to be madee to make it more comfortable or relieve chafing
Instruct the patient in the proper appllication and care of th eorthosis
Assist the patient to make the psychologic adjustment to wearing the orthosis
•Types of splints and braces and their function: Spring-loaded braces Oppose the action of unparalyzed
muscles and act as partial functional substitutes for paralyzed muscles
Resting splints Maintain a limb or joint in a functional
position while permitting the muscles around the joint to relax
Functional splints Maintain the joint or limb in a
usable position to enable the body part to be used correctly
Dynamic splints Permit assisted exercise to
joints, particularly following surgery to finger joints
Positioning and transfer
Exercise
Exercise is a prescribed form of activity designed to accomplish the following:
Preserve joint mobilityMaintain muscle toneStrengthen selected muscle
groups
Medications
antiinflammatory analgesicsTeach patients the expected
effects of the drugsHow to use them
appropriatelyHow to recognize side effects
or toxic effects.
Use of narcotic analgesics in chronic inflammatory musculoskeletal conditions is generally contraindicated.
Promoting nutrition important for individuals with musculoskeletal
problems for anyone else Patient should pay particular attention to
avoiding weight gain For many individuals with mobility problems,
however, the problem of weight and mobility becomes a vicious circle.
This cycle can be broken only by weight loss through a properly supervised reduction diet.
Nurses can help in the following ways: Teach patient the importance of a well-
balanced diet Teach patients the importance of restricting
weight gain Encourage patients to select food wisely Encourage the patient family to bring home
cooked food if the patient is not eating hospital food particularly following surgery when the patient needs to maintain a positive nitrogen balance
Surgical interventions
Indication period: Two categories: Those who have suffered trauma such
as a fracture Those who require an elective
orthopaedic procedure for correction of deformity, relief of pain, or restoration of musculoskeletal function .
•Four major objectives of orthopaedic treatment:1. Restoration or maintenance of function
of a body part
2. Prevention of deformity
3. Correction of deformity if it already exists
4. Development of the patient’s powers of compensation and adaptation if loss of function or permanent deformity is not preventable
It is important that those caring for the patient know and understand what the expected outcomes are so that care may be adapted to achieving them.
Types of surgery:
Arthrotomy
=opening of a joint
• Arthroplasty=reconstruction of a joint
Synovectomy=removal of part or all of the synovial membrane
• Osteotomy =cutting a bone to change its alignment
Arthrodesis=causing the bones of a joint to grow together by removing articular hyaline cartilage, introducing bone grafts, and stabilizing with external fixation
• Tendon transplants=moving a tendon from its usual position
